Important Safety Information
Observe the safety precautions in the following subsections when installing
your system in the rack.
WARNING:
You must strictly follow the procedures in this document to protect
yourself as well as others who may be involved. Your system may be very large
and heavy, and proper preparation and planning are important to prevent injury to
yourself and to others. This becomes increasingly important when systems are
installed high up in the rack.
Rack Stabilizer Feet
WARNING:
Installing systems in a rack without the front and side stabilizer feet
installed could cause the rack to tip over, potentially resulting in bodily injury
under certain circumstances. Therefore, always install the stabilizer feet before
installing components in the rack.
WARNING:
After installing systems in a rack, never pull more than one system
out of the rack on its slide assemblies at one time. The weight of more than one
extended system could cause the rack to tip over and cause injury.
The stabilizer feet help prevent the rack from tipping over when a system
or other component is pulled out of the rack with the slide assemblies
fully extended.
